HIstoric Earthquakes and Floods in California

I grew up with Earthquakes in California always. I have experienced thousands of earthquakes below about 5.0 in my life. Most of them you can't even feel or even know they are happening. Other scare the hell out of you when the earth rolls like a wave towards you and hits your house or place of business or destabilizes your car with a bang (only on houses or places of business). On a car or truck it might just throw you off the road or into other cars if you are driving when it happens. Or in the worst cases bridges sometimes collapse while people are driving on them like in the Loma Prieta quake near San Francisco in 1989 or the

   The 1971 San Fernando earthquake (also known as the Sylmar earthquake) occurred in the early morning of February 9 in the foothills of the San Gabriel Mountains in ...

    

   Probably the most scared I was in ANY quake was in the 1971 San Fernando quake which I thought was never going to end and might be a nuclear blast or war starting at the time just before daybreak while it was still dark out. So, it woke me up and then scared the living hell out of me because it seemed to go on forever and wouldn't stop. By the time it stopped much of Southern California was really a mess.

    

   Though must now be given by any future people coming and settling in California not only in regard to earthquakes but also now in regard to historic flooding that tends to occur every 100 to 200 years. So, right about now we are due(within 50 years or so) another great flood like happened from December 1861 to March I believe 1862 but the flood waters remained many places until June.

    

   So, something like this could happen again any time now unless Global Climate change has somehow changed all this.

    

   And that's another thing. Global climate change may be more about a Pole shift or Geomagnetic excursion both of which also change the weather dramatically and bring the protection of the magnetosphere down to about nothing from 1000 to 10,000 years each worldwide. Most scientists now believe we are either in a long term pole shift (the north pole moves to the south pole and vice versa over about 10,000 years or they believe we are in a Geomagnetic Excursion (much more common) which the last one was about 40,000 years go called the Laschamp excursion which tends to take about 1000 years.

   
   

   Both of these will leave everything on the surface of the earth unprotected from mutating Cosmic Rays and plasma from the sun which likely will cause genetic mutations to all life on the surface of the earth  unless they are living 10 feet or more underground or deep enough in the ocean.
